Ideally, your overall portfolio should beat the market average. But even the best stock picker will only win with some selections. So we wouldn't blame long term Perrigo Company plc (NYSE:PRGO) shareholders for doubting their decision to hold, with the stock down 44% over a half decade. And it's not just long term holders hurting, because the stock is down 31% in the last year. More recently, the share price has dropped a further 20% in a month. Importantly, this could be a market reaction to the recently released financial results. You can check out the latest numbers in our company report.

After losing 17% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

We know that Perrigo has been profitable in the past. However, it made a loss in the last twelve months, suggesting profit may be an unreliable metric at this stage. Other metrics may better explain the share price move.

We note that the dividend has remained healthy, so that wouldn't really explain the share price drop. While it's not completely obvious why the share price is down, a closer look at the company's history might help explain it.

The image below shows how earnings and revenue have tracked over time (if you click on the image you can see greater detail).

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business. So we recommend checking out this free report showing consensus forecasts

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Perrigo the TSR over the last 5 years was -37%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Perrigo shareholders are down 29% for the year (even including dividends), but the market itself is up 27%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 6% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
